Technical Field

[0001] This utility model relates to the field of photovoltaic panel technology, specifically a movable, foldable, and telescopic solar photovoltaic panel. Background Technology

[0002] Photovoltaic power generation is a technology that uses the photovoltaic effect at the semiconductor interface to directly convert light energy into electrical energy. It mainly consists of three parts: solar panels (modules), controllers, and inverters. The main components are made up of electronic components.

[0003] However, the current photovoltaic panels have the following main problems: (1) The photovoltaic brackets of the photovoltaic panels cannot be folded, occupying a large volume, and the number of vehicles that can load each time is limited, which increases the installation cost; (2) When it is necessary to increase the power generation, the area of ​​the photovoltaic panels cannot be increased. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a mobile, foldable, and telescopic solar photovoltaic panel to solve the problems of large photovoltaic frame volume, high installation cost, and non-adjustable photovoltaic panel area.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A movable, foldable, and retractable solar photovoltaic panel includes a movable frame. A base is hinged to the upper end of the movable frame, and the base is fixed to the movable frame via a locking assembly. A rotating shaft is rotatably connected to the base, and a drive mechanism for rotating the shaft is located inside the base. A rotating plate is fixedly connected to the upper end of the rotating shaft, and a base frame is fixedly connected to the periphery of the rotating plate. First electric telescopic rods are hinged to one end of each side of the base frame, and a flip frame is hinged to the end of the base frame away from the first electric telescopic rods. Two first electric telescopic rods are movably connected to the two sides of the flip frame, respectively. A mounting frame is welded to the top of the flip frame, and a first photovoltaic panel is installed inside the mounting frame. Mounting grooves are provided on the top surfaces of both sides of the flip frame, and second electric telescopic rods are installed in the mounting grooves. Telescopic frames are connected to the telescopic ends of the two second electric telescopic rods, and second photovoltaic panels are installed on the telescopic frames. Connecting rods are fixedly connected to the two sides of the telescopic frames away from the flip frame, and the telescopic ends of the two second electric telescopic rods are connected to the two connecting rods, respectively. Both sides of the telescopic frame are slidably connected to the flip frame via sliding assemblies. By retracting the second electric telescopic rods, the telescopic frame can be completely retracted below the flip frame.

[0007] Preferably, the movable frame includes a movable base, with casters installed at the bottom of the movable base and a support column fixedly connected to the top of the movable base. Connecting plates are welded to both sides of the upper end of the support column, and a rotating rod is rotatably connected to the two connecting plates. The lower end of the base is located between the two connecting plates, and the base is fixedly connected to the rotating rod. A rectangular opening is provided on one side of the top of the base and the support column, and the other side is fixed by a locking assembly.

[0008] Through the above technical solution, the present invention can be moved to the desired position by means of a movable frame. By setting an opening between the base and the support column, it is convenient to fold the base towards the support column to the maximum extent, thereby reducing the area occupied.

[0009] Preferably, the locking assembly includes a connecting seat connected to the support column by screws and a locking seat connected to the base by screws. The connecting seat and the locking seat are arranged opposite to each other. A handle is pivotally connected to the connecting seat. U-shaped locking rods are pivotally connected to both sides of the handle. The locking seat is provided with locking grooves that match the locking rods. After the locking rods are locked in the locking grooves, the base and the support column are stabilized.

[0010] With the above technical solution, after the base is unfolded, the handle is pulled upwards and the locking rod is locked in the locking groove of the card seat. Then, the handle is pulled downwards to lock the locking rod in the locking groove, thereby fixing the base.

[0011] Preferably, the drive mechanism includes a motor mounted in the base, a drive shaft connected to the motor via a coupling, a first gear connected to the drive shaft, and a second gear connected to the rotating shaft, wherein the first gear meshes with the second gear.

[0012] The above technical solution controls the motor to work, drives the transmission shaft to rotate, and through the cooperation of the first gear and the second gear, drives the rotating shaft to rotate, thereby driving the base to rotate, so as to drive the photovoltaic panel to rotate.

[0013] Preferably, the base frame includes connecting columns fixedly connected to the perimeter of the rotating plate, a base frame fixed to the outer end of the connecting columns, and one end of the flip frame hinged to both sides of the base frame.

[0014] Preferably, the sliding assembly includes a first guide rail and a second guide rail with a U-shaped cross-section. One side of the first guide rail is connected to the side of the flip frame by screws, and one side of the second guide rail is connected to the side of the telescopic frame by screws. The openings of the first guide rail and the second guide rail are arranged opposite to each other, and a U-shaped mounting plate is fixed to the inner side of the first guide rail and the second guide rail. Several balls are rotatably connected to both sides of the mounting plate. A slide rail is provided between the first guide rail and the second guide rail. The slide rail has grooves on both sides that match the balls. The first guide rail and the second guide rail are slidably connected to the grooves on both sides of the slide rail by balls. A first limiting plate is connected to both ends of the first guide rail and both ends of the second guide rail. A second limiting plate that cooperates with the first limiting plate is connected to both ends of the slide rail.

[0015] Through the above technical solution, the extension of the second electric telescopic rod can drive the telescopic frame to move outward. The telescopic frame drives the second guide rail to slide on the slide rail. When the second limiting plate at one end of the slide rail contacts the first limiting plate on the second guide rail, as the second electric telescopic rod continues to extend, the second guide rail pulls the slide rail, causing the slide rail to slide on the first guide rail until the first limiting plate on the first guide rail contacts the second limiting plate at the other end of the slide rail. This allows the second photovoltaic panel to be completely exposed on the outside of the first photovoltaic panel, increasing the area of ​​the photovoltaic panel.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) The second photovoltaic panel can be retracted to below the first photovoltaic panel. The first photovoltaic panel can overlap with the base frame through the flip frame, and the base frame and base can be folded down to the mobile frame, thereby greatly reducing the occupied area and improving the convenience of transportation and installation.

[0018] (2) The operation of the first electric telescopic rod can drive the flip frame to flip, thereby adjusting the angle of the first photovoltaic panel and the second photovoltaic panel. The operation of the second electric telescopic rod can move the telescopic frame out from under the flip frame, thereby increasing the area of ​​the photovoltaic panel and improving the power generation efficiency.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1:

[0031] Please see Figures 1-9 A movable, foldable, and retractable solar photovoltaic panel includes a movable frame 1, with a base 2 hinged to the upper end of the movable frame 1. The base 2 is fixed to the movable frame 1 via a locking assembly 3. Specifically, the movable frame 1 includes a movable seat 101, with casters 102 mounted on the bottom of the movable seat 101. A support column 103 is fixedly connected to the top of the movable seat 101. Connecting plates 104 are welded to both sides of the upper end of the support column 103, and rotating rods are rotatably connected to the two connecting plates 104. The lower end of the base 2 is located between the two connecting plates 104, and the base 2 is fixedly connected to the rotating rods. A rectangular opening 105 is provided on one side of the top of the base 2 and the support column 103, and the other side is fixed by the locking assembly 3. The movable frame 1 allows the panel to be moved to the desired position. By providing the opening 105 between the base 2 and the support column 103, the base 2 can be folded towards the support column 103 to the maximum extent, thereby reducing the occupied area.

[0032] The locking assembly 3 includes a connecting seat 301 connected to the support column by screws and a locking seat 302 connected to the base by screws. The connecting seat 301 and the locking seat 302 are arranged opposite to each other. A handle 303 is pivotally connected to the connecting seat 301. U-shaped locking rods 304 are pivotally connected to both sides of the handle 303. The locking seat 302 is provided with locking grooves 305 that match the locking rods. When the locking rods 304 are locked in the locking grooves 305, the base 2 and the support column 103 are stabilized. When the base 2 is unfolded upward, that is, when the base 2 and the support column 103 are in a straight line, the handle 303 is pulled upward to lock the locking rods 304 into the locking grooves 305 of the locking seat 302. Then, the handle 303 is pulled downward to lock the locking rods 304 into the locking grooves 305, thereby fixing the base 2 and fixing the base and the support column.

[0033] A rotating shaft 4 is rotatably connected to the base 2, and a drive mechanism 5 for driving the rotating shaft 4 to rotate is provided inside the base 2. Specifically, the drive mechanism 5 includes a motor 501 installed inside the base, a transmission shaft connected to the motor via a coupling, a first gear 502 connected to the transmission shaft, and a second gear 503 connected to the rotating shaft, with the first gear 502 and the second gear 503 meshing. Controlling the motor 501 to work drives the transmission shaft to rotate, and through the cooperation of the first gear 502 and the second gear 503, the rotating shaft 4 can be driven to rotate.

[0034] The upper end of the rotating shaft 4 is fixedly connected to the rotating plate 6, and the outer periphery of the rotating plate 6 is fixedly connected to the base frame 7. The base frame 7 includes connecting columns 701 fixedly connected to the periphery of the rotating plate and a base frame 702 fixed to the outer end of the connecting columns. One end of the flip frame 9 is hinged to both sides of the base frame 702. One end of each side of the bottom frame 702 is hinged with a first electric telescopic rod 8, and the end of the bottom frame 702 away from the first electric telescopic rod is hinged with a flip frame 9. The two first electric telescopic rods 8 are movably connected to the two sides of the flip frame 9, and the movable connection is a pivot connection. A mounting frame 10 is welded to the top of the flip frame 9, and a first photovoltaic panel 11 is installed in the mounting frame 10. The top surfaces of both sides of the flip frame 9 are provided with mounting grooves 12, and second electric telescopic rods 13 are installed in the mounting grooves 12. The telescopic ends of the two second electric telescopic rods 13 are connected to a telescopic frame 14, and a second photovoltaic panel 15 is installed on the telescopic frame 14. The two sides of the telescopic frame 14 away from the flip frame are fixedly connected with connecting rods 16. The telescopic ends of the two second electric telescopic rods 13 are respectively connected to the two connecting rods 16. Both sides of the telescopic frame 14 are slidably connected to the flip frame 9 through sliding components 17. By retracting the second electric telescopic rods 13, the telescopic frame 14 can be completely retracted to below the flip frame 9.

[0035] In addition, sensors such as photoresistors and photodiodes are installed around the first and second photovoltaic panels to determine the real-time position of the sun by comparing the differences in light intensity from different directions. This information is then used to control the operation of the motor, the first electric telescopic pole, and the second electric telescopic pole, thereby tracking the direction of sunlight.

[0036] In summary, the second photovoltaic panel 15 can retract below the first photovoltaic panel 11, and the first photovoltaic panel 11 can overlap with the base frame 702 via the flip frame 9. The base frame 702 and the base 2 can be folded downwards towards the movable frame 1, thus greatly reducing the occupied area and improving the convenience of transportation and installation. The operation of the first electric telescopic rod 8 drives the flip frame 9 to flip, thereby adjusting the angle of the first photovoltaic panel 11 and the second photovoltaic panel 15. The operation of the second electric telescopic rod 13 allows the telescopic frame 14 to move out from under the flip frame 9, thereby increasing the area of ​​the photovoltaic panels and improving power generation efficiency.

[0037] Example 2:

[0038] Based on Embodiment 1, the sliding assembly 17 includes a first guide rail 171 and a second guide rail 172 with a U-shaped cross-section. The first guide rail and the second guide rail have the same structure and dimensions. One side of the first guide rail 171 is connected to the side of the flip frame 9 by screws, and one side of the second guide rail 172 is connected to the side of the telescopic frame 14 by screws. The openings of the first guide rail 171 and the second guide rail 172 are arranged opposite to each other, and a U-shaped mounting plate 173 is fixed to the inner side of the first guide rail 171 and the second guide rail 172. Several ball bearings are rotatably connected to both sides of the mounting plate 173 through rotary bearings. 74. A slide rail 175 is provided between the first guide rail 171 and the second guide rail 172. The slide rail 175 has grooves 176 on both sides that match the balls. The balls 174 are slidably disposed in the corresponding grooves 176 to improve the stability and smoothness of sliding. The first guide rail 171 and the second guide rail 172 are slidably connected to the grooves 176 on both sides of the slide rail 175 through the balls 174. The two ends of the first guide rail 171 and the two ends of the second guide rail 172 are connected to the first limiting plate 177. The two ends of the slide rail 175 are connected to the second limiting plate 178 that cooperates with the first limiting plate 177.

[0039] When the second electric telescopic rod 13 extends, it can drive the telescopic frame 14 to move outward. The telescopic frame 14 drives the second guide rail 172 to slide on the slide rail 175. When the second limiting plate 178 at one end of the slide rail 175 contacts the first limiting plate 177 on the second guide rail 172, as the second electric telescopic rod 13 continues to extend, the second guide rail 172 pulls the slide rail 175, causing the slide rail 175 to slide on the first guide rail 171 until the first limiting plate 177 on the first guide rail 171 contacts the second limiting plate 178 at the other end of the slide rail 175. That is, through two stages of displacement, the telescopic frame 14 can make the second photovoltaic panel 15 completely exposed outside the first photovoltaic panel 11, increasing the area of ​​the photovoltaic panel.
